Is the square root of 72 x 16 irrational?
Yes.
What cubed equals 72?
The cube root of 72 is an irrational number; to 3 decimal places it is 4.160.
How do you determine that 72 isn't a square number?
Because the square root of it is an irrational number
Can you find irrational numbers between 7 and 8?
72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
Is the square root of 72 a rational or irrational number?
The square root of 72 is an irrational number. Since 72 is not a perfect square, the decimal is endless. (just like the value of pi)

What is the best approximation for the square root of 72?
The square root of 72 is an irrational number and there is no such thing as a best approximation for any irrational number. By definition, all irrational numbers are represented by infinitely long decimal strings and it is always possible to improve the approximation by calculating the value to one more decimal place. 8.48528 should be sufficiently accurate for most purposes.
Can you find irrational numbers between 7 and 8?
72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
What is the sqaure root of 72?
The square root of 72 is 6x(sqrt2). You can find this by breaking 72 down into its prime factors (2x6x6 or 2x62). You can then take the square root of each part which means the 62 will become 6 and then because the sqrt2 is an irrational number it is left under the sqrt sign.
